Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...
For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...
A simple mechanism could underlie the growth and self-replication of protocells - putative ancestors of modern living cells - suggests a study publishing September 3 in Biophysical Journal. Protocells ...
"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." Until now, cells dividing by mitosis were thought to grow round and then split into two identical, ...
Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
The filamentous bacterium Corynebacterium matruchotii splitting into multiple cells at once, a rare kind of cell division called multiple fission. C. matruchotii is one of the most common bacteria ...
